Description
technical field [0001] The invention relates to an emulsion preparation device, in particular to a glass capillary microfluidic device designed for increasing the output of the emulsion and having the characteristics of multi-dimensional, fast and uniform emulsion preparation. Background technique [0002] Emulsion is a highly structured fluid system, which can be divided according to different components: single emulsion with only one phase, double emulsion with two-phase nested structure, and multiple emulsion with more than two phases. Emulsions are widely used in drug release, drug delivery, biomaterials, biochemistry, and cosmetics industries. With the development of science and technology, the requirements for emulsion quality and output are getting higher and higher in production. Traditional emulsion preparation methods, such as stirring method, membrane emulsification, etc., will cause waste of raw materials, low preparation efficiency, and poor monodispersity of e...
